Bc it known that l, Anonimi KENT, n. citizen of the Unit-cd States oiAmerica, and n i resident of the horoughvof Brooklyn, countyY i ol'Kings, citjiY und State of New York, have invented certain new anduseful .lm'provei ments in Body-Forming Machines, of which thc followingis n. specification.

'l`hc prcscni invention relates generally to liotly-iormcrs forproducing.V the bodies ol' cans or other vcsselsl'roin a llat Sheet ofmalcrinl,

'lhc object of the present invention is to thc machine ns unich aspossible, st the ssme time making: thc machine morelcil'ective in itsoperation and capable ot turning out s more pcrl'ect product.

'l`o this cnil the invention consists in the combinations ol' parts sindfeatures of con- Astrut-tion, as will more fullyv hereinafter apln theaccompanying drswings'the invern' tion luis been embodied in s practicalma chine, showingr thc preferred form; but, it is obvious that u. widedeparture may he made from the` spocilic construction shown withoutpassing beyond the boundaries of the invention.

1n the said drawings, Fiure l is a. rear elevstion of o machine with thestripping mechanism removed embocl in'g my invention. Figs. 2 and 3 aredetail views of the means for the parts in two different positions. Fig.4 is a. pion View ol the machine, showing more particularly the gearingand transmission mechanism. Fig. .5 is a, detail View of tbe moans foradjusting the length of the stroke of the expander for the horn. Fig. 6is a, sectional view leken throu'glrthe hook-forming members on theline-6 6 of Fig. 4. Fig. 7 is a detail View ol' one of the adjustablegages of the hook-forming members.

Similar numerals indicate corresponding parts in the different views.

l indicates s framework of any suitable construction lor properlymounting the parts. The main elements carried by this frame are twolmolcforming members 2 and 3, the horn 4, the hhmlvforming mechanism 5lor folding the hlnnli around the horn, the hammer 6, and the strippinvmechanism The general similar to other nmchincs of the sumo churucterund may he bricll)l indicated by .slutingf that 8 is the muinshaltrunningr lrmisvcrscly ofthe machine und passing through thchookforming members. Upon this shrill is mount ed a. pulley J or othermoans wher-chi moY tion can he imported to thcsniil shul't und lurthcr,two ruiter-gears il) und ll for im unlimimotion to the two cmu-shafts lnml lll hi meshing with the unter-gears 14 und l5.

Arranged centrally of the muchinc is :i sheet-feeding device 16, haringthc usunl iingers, as 17, for progressing thc sheet from om` port to theother through thc machine. This sheet-feeding device isopcrntedconveniently from the main Shaft in thc usual munncr hy means of thecrank 1S, mounted on thc moin shaft, and link 19 and rod 2U', attachedto thc crank 21, mounted on the shrill Ll pnrullcl lo thc mainslmi't,wl1ich lutter shaft is provided with a suitable connection, ns22%, lor opcrnt ing the sheet-icedingr device and also for operating thestripping mechanism iu the usmil manner.

The forming mechanism 5 travels in tho ways 24, and the hummer (itravels in thc ways 25, one above and the other below thc horn. Suitablereciprocating motion is imparted to the forming mechanism and hammer bineens of the cams 26 and 27 throuwh suitsb e connections, as 38 sud 29,in n wellknown manner. Mounted upon the shaft lil is further a cam 3Ufor operating the expanding mechanism 31 of the horn.

As previoushT pointed out, this general m'- rsnqenient is wel known andneed not he dcscribed more fully here.

The hook-forming members are constructed ns follows: Adjustubly mountedin tht` framework on either side of the path ol progression of the sheetare the hook-forminoT boxes 32 and 33. These hook-forming boxes act asstandards or frames for supporting thc ports comprising the hook-formingmembers. As the construction of these two hook-forming members issubstantially the same, oni)r one will he described, and the dill'crcncein structure between the two will then be pointed out later. Passingthrough the hook`ormin;r boxes is the main shaft which carries thc twocams 34 and 35. Zhi indicates n chimpv ing-jaw for the sheet pivotcd et257 on the hox and adapted to hold the sheet between itscli' and thestationary clmnping-jaw 3S, attached IOC to the box below the plane inwhich the sheet travels. 39 is a friction-roll moving with the jaw 36and adapted to be operated by the cam 34 to clamp the sheet in the usualmanner. 40 indicates a gage adjustable horizontally and spring-seated,so as to be capable of a vertical movement. The distance of this gagefrom the clam ing-j aws determines the wldth of the hook to eformed. 41represents fixed strai ht guideways inclined throughout their lengt inwhich slides the hook-forming tool 42, having the friction-roll 43. Oneof the clampin -jaws is provided with a lip or beveled sur ace 44, andthe angle at whic-h the hook-forming tool travels corresponds to theangle of this li or beveled surface 44. The gage 40 norma ly rojectsabove or below, as the case may be, t e edge of the blank, so as to actas a ositive stop. Upon the rotation of the shallJ 8 and at the propermoment when the sheet has assumed its position on the lower jaw 38 thecam 34 will cause the upper jaw 36 to clamp 4the sheet in the propermanner. The action of the cam now causes the hook-forming tool to movein the guides, fixed in an inclined position, and as it moves upward ordownward, as the case may be, it will move in under or over the edge ofthe blank and will cause the gage to recede as it turns the edge of thetin over the lip or beveled surface 44.

In the case of the hook-forming member 2 the gage 4() normallyrests ontop of the forming-tool 42 and is spring-seated 1n the bracket 45, asshown. The bracket 45 is mounted on the hook-forming box and isadjustable in a horizontal direction by means of the screw 46 assingthrough the box and through the lock 47 of the bracket 45, which bracketis free to move in the slot 48 of the box.

In the case of the hook-forming member 3 the construction issubstantially the same, the only difference being that in this case alip 49 is formed on the clamping-jaw 38 instead of the clamping-jaw 36.Further, the formin -tool moves 1n a downwardl -inclined irectioninstead of in an upward y-inclined direction, as in the case of themember 2. In addition to this the gage 5() is springseated in the box,as shown, and is adjustable horizontally by means of the screw 51, bywhich it is connected to the box.

The blank-forming mechanism 5, which acts to fold the blank around thehorn,is constructed in such a manner that the blank is foldeduninterruptedly around the said horn. 52 indicates avertically-reciprocating slider moving in the ways 24 and provided witha primary former 53, having a yielding movement by reason of the spring54. Carried by this rimar former are two wings 55 and 56, whic areivotally attached at 57 and 58. 59 and 60 i icate. two connectionspivoted at 61 and 62 to the slider 52 and pivoted with their other endson the wings 55 and 56 eccentrically with relation to the pivots 57 and58. These connections are adjustable by being threaded in oppositedirections in a wellknown manner. One of these connections is further soconstructed as to keep one of the wings sli htly ahead of the other, soas to allow the ooks of the blank to properly engage with each otherwhen folding 1t around the horn. To this end the connection 59 isyielding, while the connection 6() is rigid. In the present instance thespring 63 is provided in conjunction with the connection 59, which tendsto keep the wing 55 a slight distance ahead of the win' 56. As the blankcomes in position under t e horn the slider 52 will be caused to moveupward and the rimary former 53 will clamp the blank on t e horn andpartially fold the tin, as shown in Fig. 2. The continued motionof theslider 52 will counteract the effect of the spring 54 and move the slider up close to the primary former, as shown in Fig. 3, this motioncausing the win s to turn aroundl their pivots, thereby olding the blankproperly around the horn and causing the hooks ofthe same to interlock.The horn is now expanded, thereby causing the connection 59 to recedeslightly, owing to the s rin 63. The hammer 6 now descends and c enc esthe seam, the horn collapses, the slider 52 returns, and the strippingmechanism removes the completed body from the horn in the usual manner.

In the prior art it has been customary to pivot the movable Hap of thehorn at a oint out of alinement with the center oi the orn. In theconstruction of machines where it is desired to present substantially acylinder when the horn is expanded the pivoting of the Hap at this pointproduces a decided step or recess in the surface of the horn when thelatter is colla sed and into which recess the blank is liab e to bucklewhen it is folded around the said horn, thereby preventing the hooksfrom interlocking and thus spoiling the can-body. In the presentinstance I provide a horn which presents a Substantially continuoussurface when in its collapsed position and which when expanded formssubstantially a complete cylinder. In the present instance this is accomlished by constructing the horn'with a ed member 64 and a flap ormovable member 65, pivoted at 66 on the fixed member, which is a pointin vertical alinement with the center of the horn. In this way when thehorn is collapsed there is substantially no step or recess formed in itssurface,.and in this Way the spoilin of a great many can-bodies isprevented. he horn is normally held in its collapsed position by meansof the spring 67, and the fla is provided with.a pin 68, against whicacts the tapered plu or expander 69 'in a wellknown manner Ior causingthe horn to expand. This tapered (plug, as previously pointed out, isoperate from the cam Boat IOO IIO

the proper eriods by means of the expanderlever 31. llhis lever 31 ispivoted on the stud 70, mounted on the bracket 7l, which is attached tothe framework by means oi' the screw 72, passing through the saidbracket and passing through the lower part of the stud 70, which extendsinto the slot 73 of the bracket 7 l. By loosening up on the lockingbolt74 this stud can be adjusted back and forth, whereby the exact amount ofexpansion of the horn desired can be obtained and whereby any Wear ofthe members can be taken up and com ensated for.
